An article in Experimental Brain Research [€œSynapses in the Granule Cell Layer of the Rat Dentate Gyrus: Serial- Sectionin Study€ (1996, Vol. 112(2), pp. 237€“243)] showed the ratio between the numbers of symmetrical and total synapses on somata and azon initial segments of reconstructed granule cells in the dentate gyrus of a 12-week-old rat:

(a) Use the data to test H₀: σ² = 0.02 versus H₁: σ² ‰  0.02 using α = 0.05.

(b) Find the P-value for the test.
